自动重合闸的应用建立在绝大多数线路故障为瞬时性的基础上,在出现冰冻等自然灾害的情况下,其盲目重合的弊端将突显,而自适应重合闸通过故障性质的判别可以弥补这一缺陷。在自适应重合闸评价方法应增加正确不重合率指标,但在当前在线的故障性质判别方法并不成熟的前提下,可沿用常规重合闸的评价方法,但不应据此错误理解自适应重合闸所产生的效益。还探讨了自适应重合闸的可控性以及试运行中应注意的事项。
The application of automatic reclosing is based on the instantaneous nature of the vast majority of line faults. In the event of natural disasters such as freezing, the drawbacks of blind coincidence will be highlighted, and adaptive reclosing can make up for this by identifying the nature of the fault A defect. In the method of adaptive reclosing evaluation, the correct index of misalignment should be increased. However, under the precondition that the method of online fault identification is not mature, conventional reclosing evaluation method can be used. However, adaptive reclosing should not be misunderstood Gates generated benefits. It also discusses the controllability of adaptive reclosing and the matters needing attention in the trial operation.
